ADJUSTABLE WINDOW-CHAIR.

Application filed November 22, 1915.

T 0 all whom it may concern Be it known that 1, JOHN PFAFF, a citizen of the United States, residing at Montgomcry, in the county of Lycoming and State of Pennsylvania, have invented a new and useful Adjustable indow-Chair, of which the following is a specification.

The present invention appertains to window chairs, and aims to provide a novel and improved chair structure applicable to a window, whereby a person seated in the chair can readily clean or paint the outside of the window, without danger of falling.

It is the object of the invention to provide a window chair having novel means for holding it in place when applied to a window, and which is adjustable to accommodate windows of various widths, the device also being foldable so that it can be readily stored and handled.

l/Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a plan view of the chair. Fig. 2 is a vertical section thereof as applied to a window. Fig. 3 is a front elevation of the chair, a portion of the window casing being shown in dotted lines.

The chair embodies a seat and back which are of somewhat similar construction. The seat embodies a pair of parallel side rails 1 having secured to their inner sides, cleats 2 upon which are secured the remote ends of transverse slats 3 having their adjacent ends overlapped. A strap 4: is terminally secured to the inner end of each slat 3 and slidably embraces the companion slat, whereby the slats are slidably connected to enable the rails or bars 1 to be moved toward and away from one another, the seat thus being adjustable transversely to various widths.

The back embodies a pair of parallel side stiles 5 having secured to their inner sides, cleats 6 to which are secured the remote ends of transverse slats 7 which have their adjacent ends overlapped. A strap 8 is terminally secured to the inner end of each slat 7 Specification of Letters Patent.

and slidably embraces the companion slat, whereby the slats 7 the same as the slats 3, are slidably connected to enable the stiles 5 to be moved toward and away from one another, whereby the back is adjustable transversely the same as the seat.

The lower terminals of the stiles 5 project below the rails 1, and are provided with rabbets or notches 9 to fit the sill or ledge at the outer side and lower end of the window, blocks 10 being preferably secured to the forward edges of ,the stiles 5 adjacent the upper ends of the rabbets 9 to enlarge said rabbets and to reduce the liability of thri stiles accidentally disengaging from the sil The seat and back are hingedly connected, and to this end a pair of upwardly projecting plates 11 is secured to the sides of each rail 1 adjacent the rear end thereof, and a pair of forwardly projecting plates 12 is secured to the opposite sides of each stile 5 slightly above the lower end thereof, said plates being secured to the rails and stiles by means of screws or other securing elements 18. The projecting portions of the plates 11 have longitudinal series of apertures 14, and the projecting portions of the plates 12 have vertical series of apertures 15. Two bolts 16 are employed for pivotally connecting the seat and back, it being understood that the stiles 5 are disposed between the rear ends of the rails 1. Each bolt 16 is inserted through alining apertures 14 of one pair of plates 11 and through alining apertures 15 of the companion plates 12, and wing and thumb nuts 17 are threaded upon the bolts to hold them in place.

By inserting the bolts 16 through the various apertures 15, the back can be adjusted vertically, and by inserting the bolts through the various apertures 14, the back can be ad justed forwardly and rearwardly relative to the seat, in order that the seat and back can be properly adjusted to accommodate various windows. The hinged connection of the seat and back also allows them to be swung snugly together for compact storage or transportation.

The rails 1 are provided with means adjacent their forward ends for engaging the window casing or frame to prevent the outward movement of the seat when the chair is in place, and to this end blocks 18 are secured upon the rails 1 by means of bolts 19 engaged through said blocks and rails, and

having wing nuts 20 threaded thereon. These blocks 18 project in opposite directions so as to overlap and bear against the inner side of the window casing, and the blocks 18 are provided with depending lugs 21 hearing against the outer sides of the rails 1,for preventing the blocks from swinging relative to the rails 1. The blocks 18 are thus held in outstanding position to bear against the window casing, for holding the seat in place within the window.

In using the chair, the back can be adjusted vertically, and forwardly and rearwardly relative to the seat to the proper'position, and the seat and back can also be extended or contracted according to the width of the window. The chair will then properly accommodate the window, the blocks 18 bearing against the inner side of the casing, and the lower ends of the stiles 5 fitting the sill or ledge for holding the back in positions A person may then sit upon the chair for comfortably and conveniently washing or painting the outside of the window.

The rails 1 are also provided with horizontal apertures or bores 22 therethrough for the reception of the bolts 19 in order that the blocks 18 can be applied to the rails in a vertical position.

Having thus described the invention, what is claimed as new is A window chair embodying a seat having side rails, a back having side stiles, the rails plates having vertical series of apertures,

pivot elements engageable through said ap ertures whereby the back can be adjusted vertically and forwardly and rearwardly relative to the seat, the lower ends of the stiles projecting below the seat and having still engaging means.

In testimony that I'claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.

JOHN PFAFF.
